Some modern vehicles may display a "Service Airbag" or "Seat Belt Fault" message on the driver information center [2].

Pinched, frayed, or broken wires in the B-pillar or under-seat area can disrupt the circuit [19, 21]. Some modern vehicles may display a "Service Airbag"

In many cases, the computer will disable the entire airbag system as a precaution when this code is active [6, 7]. Typical Causes Typical Causes Using a "load tool" or specialized

Using a "load tool" or specialized resistor to simulate a working pretensioner can help determine if the problem is in the wiring or the pretensioner itself [4, 18]. This code typically points to a malfunction in

Because SRS systems contain explosive components, specialized diagnostic tools are required to test the circuit safely without accidental deployment [2, 6].

Code is a safety-critical diagnostic trouble code (DTC) that indicates a fault within your vehicle's Supplemental Restraint System (SRS) —commonly referred to as the airbag system [2, 16]. This code typically points to a malfunction in the deployment loop for a specific safety component, often the passenger seat belt pretensioner [2, 18]. What is Code B0022?
